"Through a series of case studies drawn from Central Europe, the United States, and Britain, The Most Secret Quintessence of Life explores how the notion of sex hormones enabled scientists to remap the human body, encouraging hopes that glandular interventions could cure ills, malfunctions, and even social deviance in ways inconceivable to previous generations. Many of these dreams failed, but their history, Chandak Sengoopta shows, takes us into the very heart of scientific medicine, revealing how even its most arcane concerns are shaped by cultural preoccupations and anxieties."--Jacket.
